I’m planning on doing a wipe/factory reset on my moto g4, and I need to know what that will do to the sd card. Should I reformat it as a portable before I wipe my phone? There’s nothing important on there.
That depends on how the MicroSD card is currently formatted. My understanding if it’s formatted as adoptable storage and left in the phone during a factory reset is it will be wiped along with internal memory. If it’s already formatted as adoptable storage and removed prior to the factory reset; it won’t be wiped but also won’t work as adoptable storage post reset. At that point, it would need to be formatted either as adoptable or portable storage depending on how you want to use the card going forward.
